There are, of course, institutions called libraries that will still rent you books for free. But if they are out of your requested reading, there are websites like Bookmooch.com. This site lets you exchange books with bookworms from around the world. If audiobooks are more to your liking, websites like LibriVox.org offer free downloads of audiobooks in the public domain. Audible.com, a popular audiobook website, offers a free download with a 30-day trial.
